Confirm it can access them, and query them? SSHd does reverse lookup on connecting clients before allowing connection. If it cannot connect to the specified DNS servers, it will often appear as a timeout. </p> <p>If it did fix the problem, I'd have trouble explaining why the 'wake up work-around' you've been using works...</p> <p>Also - anything appear in your system logs? Specifically during the time period of a 'timed-out' connection? sshd will likely write to /var/log/messages and /var/log/auth.log (or similar)</p> <p>Cheers,<br /> Shaggy.</p> Tue, 21 Apr 2009 16:23:48 +0000 Shaggy comment 1240664 at https://www.webmaster-forums.net
